1. All voltages referenced to device GND.  
2. The parameters listed on Table 3 are controlled via design or process and are not directly tested. These parameters are characterized  
on initial design release and upon design changes which would affect these characteristics.  
3. CL = 50pF, RL = 200K, Input TR, TF < 20ns.  
4. From Up/Down, Binary/Decode, Carry In, or Preset Enable Control Inputs to Clock Edge.  
5. If more than one unit is cascaded in the parallel clocked application, tr CL should be made the sum of the fixed propagation delay at  
15pF and the transition time of the carry output driving stage for the estimated capacitive load. This measurement was made with a de-  
coupling capacitor (>1µF) between VDD and VSS.  
6. From Carry In to Clock Edge.
